Methods from Deref<Target = UdpSocket>
pub fn local_addr(&self) -> Result<SocketAddr, Error>
[src]
pub fn local_addr(&self) -> Result<SocketAddr, Error>
Returns the socket address that this socket was created from.
Examples
use mio::net::UdpSocket; let addr = "127.0.0.1:0".parse()?; let socket = UdpSocket::bind(&addr)?;
pub fn try_clone(&self) -> Result<UdpSocket, Error>
[src]
pub fn try_clone(&self) -> Result<UdpSocket, Error>
Creates a new independently owned handle to the underlying socket.
The returned UdpSocket
is a reference to the same socket that this
object references. Both handles will read and write the same port, and
options set on one socket will be propagated to the other.
Examples
use mio::net::UdpSocket; // We must bind it to an open address. let socket = UdpSocket::bind(&"127.0.0.1:0".parse()?)?; let cloned_socket = socket.try_clone()?; assert_eq!(socket.local_addr()?, cloned_socket.local_addr()?);
pub fn send_to(&self, buf: &[u8], target: &SocketAddr) -> Result<usize, Error>
[src]
pub fn send_to(&self, buf: &[u8], target: &SocketAddr) -> Result<usize, Error>
Sends data on the socket to the given address. On success, returns the number of bytes written.
Address type can be any implementor of ToSocketAddrs
trait. See its
documentation for concrete examples.
Examples
use mio::net::UdpSocket; let socket = UdpSocket::bind(&"127.0.0.1:0".parse()?)?; // We must check if the socket is writable before calling send_to, // or we could run into a WouldBlock error. let bytes_sent = socket.send_to(&[9; 9], &"127.0.0.1:11100".parse()?)?; assert_eq!(bytes_sent, 9);
pub fn recv_from(&self, buf: &mut [u8]) -> Result<(usize, SocketAddr), Error>
[src]
pub fn recv_from(&self, buf: &mut [u8]) -> Result<(usize, SocketAddr), Error>
Receives data from the socket. On success, returns the number of bytes read and the address from whence the data came.
Examples
use mio::net::UdpSocket; let socket = UdpSocket::bind(&"127.0.0.1:0".parse()?)?; // We must check if the socket is readable before calling recv_from, // or we could run into a WouldBlock error. let mut buf = [0; 9]; let (num_recv, from_addr) = socket.recv_from(&mut buf)?; println!("Received {:?} -> {:?} bytes from {:?}", buf, num_recv, from_addr);
pub fn send(&self, buf: &[u8]) -> Result<usize, Error>
[src]
pub fn send(&self, buf: &[u8]) -> Result<usize, Error>
Sends data on the socket to the address previously bound via connect(). On success, returns the number of bytes written.
pub fn recv(&self, buf: &mut [u8]) -> Result<usize, Error>
[src]
pub fn recv(&self, buf: &mut [u8]) -> Result<usize, Error>
Receives data from the socket previously bound with connect(). On success, returns the number of bytes read and the address from whence the data came.
pub fn connect(&self, addr: SocketAddr) -> Result<(), Error>
[src]
pub fn connect(&self, addr: SocketAddr) -> Result<(), Error>
Connects the UDP socket setting the default destination for send()
and limiting packets that are read via recv
from the address specified
in addr
.

[src]
pub fn set_broadcast(&self, on: bool) -> Result<(), Error>
Sets the value of the SO_BROADCAST
option for this socket.
When enabled, this socket is allowed to send packets to a broadcast address.
Examples
use mio::net::UdpSocket; let broadcast_socket = UdpSocket::bind(&"127.0.0.1:0".parse()?)?; if broadcast_socket.broadcast()? == false { broadcast_socket.set_broadcast(true)?; } assert_eq!(broadcast_socket.broadcast()?, true);

pub fn join_multicast_v4(
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<(), Error>
[src]
pub fn join_multicast_v4(
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<(), Error>
Executes an operation of the IP_ADD_MEMBERSHIP
type.
This function specifies a new multicast group for this socket to join.
The address must be a valid multicast address, and interface
is the
address of the local interface with which the system should join the
multicast group. If it's equal to INADDR_ANY
then an appropriate
interface is chosen by the system.
pub fn join_multicast_v6(
&self,
multiaddr: &Ipv6Addr,
interface: u32
) -> Result<(), Error>
[src]
pub fn join_multicast_v6(
&self,
multiaddr: &Ipv6Addr,
interface: u32
) -> Result<(), Error>
Executes an operation of the IPV6_ADD_MEMBERSHIP
type.
This function specifies a new multicast group for this socket to join.
The address must be a valid multicast address, and interface
is the
index of the interface to join/leave (or 0 to indicate any interface).
pub fn leave_multicast_v4(
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<(), Error>
[src]
pub fn leave_multicast_v4(
&self,
multiaddr: &Ipv4Addr,
interface: &Ipv4Addr
) -> Result<(), Error>
Executes an operation of the IP_DROP_MEMBERSHIP
type.
For more information about this option, see
join_multicast_v4
.
pub fn leave_multicast_v6(
&self,
multiaddr: &Ipv6Addr,
interface: u32
) -> Result<(), Error>
[src]
pub fn leave_multicast_v6(
&self,
multiaddr: &Ipv6Addr,
interface: u32
) -> Result<(), Error>
Executes an operation of the IPV6_DROP_MEMBERSHIP
type.
For more information about this option, see
join_multicast_v6
.
pub fn set_only_v6(&self, only_v6: bool) -> Result<(), Error>
[src]
pub fn set_only_v6(&self, only_v6: bool) -> Result<(), Error>
Sets the value for the IPV6_V6ONLY
option on this socket.
If this is set to true
then the socket is restricted to sending and
receiving IPv6 packets only. In this case two IPv4 and IPv6 applications
can bind the same port at the same time.
If this is set to false
then the socket can be used to send and
receive packets from an IPv4-mapped IPv6 address.
pub fn only_v6(&self) -> Result<bool, Error>
[src]
pub fn only_v6(&self) -> Result<bool, Error>
Gets the value of the IPV6_V6ONLY
option for this socket.
For more information about this option, see set_only_v6
.
pub fn take_error(&self) -> Result<Option<Error>, Error>
[src]
pub fn take_error(&self) -> Result<Option<Error>, Error>
Get the value of the SO_ERROR
option on this socket.
This will retrieve the stored error in the underlying socket, clearing the field in the process. This can be useful for checking errors between calls.
